Meela Nais and Anck Namun. other people tend to ignore this fact when watching the movie

I swear Im the only person to pay attention to what really goes on in the movie.

Meela is the physical appearance "reincarnation" of Anck Namun and thats it. Then they do the ritual to transfer Anck's soul into Meela's body then that when Anck Namun is "resurrected

But then in the end, from all the stress and crazyness of the supernatural stuff going on, Meela was able to break free and kicked out Anck' soul and got away from Imotep leaving him to die.

then Meela herself met an ironic fate of being devoured by scorpions or scarab beetles and she was sent to maybe the Egyptian underworld too i guess i dunno.
